What Is MicroTESE Surgery?

MicroTESE (Microscopic Testicular Sperm Extraction) is the procedure of searching for sperm within the testicular tissue under a microscope in men who have no sperm in their semen (azoospermia). Today, it is considered one of the most advanced sperm retrieval methods in male infertility.

This method is applied especially to obtain sperm for in vitro fertilization (ICSI) treatment.

In Which Situations Is MicroTESE Performed?

MicroTESE is generally applied in the following patients:

  • Non-obstructive azoospermia (sperm production disorder)
  • The absence of any sperm in the semen
  • Patients in whom sperm could not be found with previous TESE
  • Infertility of genetic or testicular origin

How Is MicroTESE Performed?

The procedure is carried out in an operating room environment and usually under general anesthesia.

Preparation

  • The patient is placed under anesthesia
  • The testicular area is made sterile

Surgical Opening

  • The testicle is opened with a small incision
  • The testicular tissue is examined under a microscope

Microscopic Examination

  • A high-magnification surgical microscope is used
  • Areas where there may be sperm production are evaluated one by one

Tissue Retrieval

  • Small pieces of tissue are taken from areas with a chance of sperm production
  • Sperm is searched for in the laboratory

If Sperm Is Found

  • The sperm found can be frozen
  • It is used the same day or later for in vitro fertilization (ICSI)

The Advantages of MicroTESE

A Higher Chance of Finding Sperm

  • It is more successful than classic TESE
  • It is effective especially in severe azoospermia

Less Tissue Damage

  • Selective retrieval is performed under a microscope
  • Healthy testicular tissue is preserved

Repeatability

  • It can be performed again if necessary

What Is the MicroTESE Success Rate?

The success rate varies according to the patient’s condition:

  • On average, a 40-60% chance of finding sperm
  • The rate may decrease with genetic factors
  • It varies according to the hormonal and testicular condition

Is MicroTESE a Painful Procedure?

  • The procedure is performed under general anesthesia
  • The patient does not feel pain
  • There may be mild pain and swelling afterward

The Process After MicroTESE

  • Discharge usually the same day or the next day
  • Return to daily life within 1 to 2 weeks
  • Sexual activity is usually permitted after 2 to 3 weeks

What Are the Possible Risks?

As with any surgical procedure, there are some risks:

  • Pain in the testicle
  • Swelling or bruising
  • Infection
  • Rarely, a decrease in testicular function

The Difference Between MicroTESE and Classic TESE

PrecisionLowHigh

Who Is MicroTESE Suitable For?

  • Men with no sperm in the semen
  • Couples for whom in vitro fertilization is planned
  • Patients in whom sperm could not be found with other methods

Summary

MicroTESE is an advanced surgical method that enables sperm to be searched for within the testicle under a microscope in azoospermia patients. Today, it is one of the most important treatment options in male infertility and offers the chance of having a biological child in many patients. The success rate increases with the right patient selection and an experienced surgical team.
